The interviewer asks: "A model provider announces that the model version your production system depends on will be deprecated and shut off in ninety days. How do you plan the migration?" Which answer best demonstrates Model Deprecation Migration Engineer expertise?
Option B is strongest because it starts immediately, inventories all dependent call sites, quantifies regressions per feature, prioritizes by impact, and builds in a real buffer before the hard deadline. Option A risks running out of runway once the real scope of evaluation and fixes becomes clear, especially close to a hard deadline. Option C creates a last-minute, high-risk simultaneous cutover with no time to catch or fix regressions before the deadline. Option D is not a reliable plan since the provider may not grant an extension, leaving no fallback if the request is refused.

The interviewer asks: "After migrating to a new model version, one specific feature's output quality quietly degraded, but this was not caught until customers complained weeks later. How do you prevent this in future migrations?" Which answer best demonstrates Model Deprecation Migration Engineer expertise?
Option B is strongest because it builds systematic, feature-specific regression coverage, adds post-migration monitoring with a defined observation window, and establishes a fast feedback loop from support back to the migration team. Option A repeats the same process that already failed to catch a real regression and treats a systemic gap as a one-off. Option C is a disproportionate response that reintroduces dependency on a model that is being shut off, when only one feature actually needs attention. Option D leaves a known quality regression unaddressed indefinitely, harming the feature's users with no plan to fix it.

The interviewer asks: "Some prompts in your codebase were tuned very specifically around quirks of the old model version, and a straightforward swap to the new model changes behavior in subtle, hard-to-spot ways. How do you handle prompts like this during migration?" Which answer best demonstrates Model Deprecation Migration Engineer expertise?
Option B is strongest because it proactively identifies prompts likely to be quirk-dependent, re-tunes them deliberately against the new model with real test cases, and documents findings to speed up future migrations. Option A assumes compatibility that is specifically unlikely given prompts known to be tuned to old-model quirks, risking exactly the subtle regressions described. Option C wastes effort rewriting prompts that were never quirk-dependent and did not need changes, while not necessarily being more careful about the ones that do. Option D is purely reactive and lets known-risky prompts ship unreviewed, discovered only after customer impact.

The interviewer asks: "Leadership wants to migrate to a cheaper model to cut costs, separate from any deprecation deadline, but is only focused on the cost savings and not asking about quality impact. How do you make sure this trade-off is evaluated properly?" Which answer best demonstrates Model Deprecation Migration Engineer expertise?
Option B is strongest because it proactively runs the same rigorous quality evaluation regardless of what was explicitly asked, and presents findings in business terms that let leadership make a deliberate, informed trade-off rather than an accidental one. Option A silently complies and risks shipping a hidden quality regression that leadership never had visibility into. Option C refuses to help with a legitimate business goal instead of constructively surfacing the missing risk information. Option D evaluates only the one feature leadership happened to name, leaving every other feature's quality impact unassessed and unknown.
5 / 5
The interviewer asks: "How do you design your systems so that future model deprecations are routine, low-stress events instead of each one becoming a fire drill?" Which answer best demonstrates Model Deprecation Migration Engineer expertise?
Option B is strongest because it maintains a living dependency inventory, reusable evaluation tooling, documented quirk-sensitive prompts, and proactive awareness of provider deprecation patterns, turning each future migration into a known playbook execution. Option A repeats the same reinvention-under-pressure pattern for every future deprecation, guaranteeing recurring fire drills. Option C deliberately skips the investment that would prevent the fire-drill pattern, prioritizing short-term effort savings over long-term stability. Option D perpetually defers the improvement work, ensuring the next migration is handled with the same ad hoc urgency as the last one.
